Eye Prescription For Contact Lenses?

Hello!!


I've been interest in buying contact lenses
in Tokyo (coloured ones).

But I was wondering how to say if I'd have no eye prescription (-0.00) ?


Thank you.

"coloured contact lens" is called カラコン(kara-kon) that is an abbreviation for カラーコンタクトレンズ(karaa kontakuto renzu).
"no power lens" is usually called どなしレンズ(do-nashi renzu) or どのないレンズ(do-no-nai renzu).
In this case, ど(do; angle) means the power of lens.
Store staff can understand "do-nashi".
And only buying do-nashi, no prescription is required.

BTW, I import them online because they are costly in Japan.

Oh I see,
thank you very much ,this
helped me out a lot !!!
